摘要： A non-invasive NMR based apparatus for measuring a food attribute (moisture, sugar content) in food products comprises a magnetic chamber, an RF pulsing device attached to the magnetic chamber, a sensor receiver, and a data processing unit in communication with the sensor receiver. The pulsing device exposes the food ingredients/snacks to an RF field and produces an NMR response signal that is detected by the sensor receiver. The data processing unit quantitatively measures a food attribute of the food product based on the NMR response signal.
